Ball valve gas, 6/4" FF - lever

Product detailed description

This ball valve is commonly used in gas supply systems for residential and commercial buildings, including heating and ventilation installations. It is suitable for applications where a reliable shut-off is required, such as in gas lines feeding boilers, water heaters, or industrial equipment. The valve is designed for use in systems operating under low-pressure conditions and is intended for installation by qualified technicians or contractors working with gas piping systems.

Its compact design and lever operation allow for quick and easy actuation, making it suitable for both manual control and integration into automated systems. The valve is intended for use in dry environments and should be installed in accordance with local gas safety regulations and manufacturer guidelines.

The operating temperature range of -30°C to +60°C makes this valve suitable for cold environments and typical indoor conditions. The PN 5 rating indicates that it is designed for low-pressure gas applications. These parameters are essential for ensuring correct sizing and compatibility with the system's operating conditions.

Installation and connection

The valve is equipped with a 6/4 inch female-female (FF) thread, which allows for direct connection to standard gas piping. Prior to installation, the threads should be cleaned and inspected for damage. A sealing compound or PTFE tape should be applied to the threads to ensure a leak-tight connection. The lever should be positioned for easy access and should not be obstructed by surrounding components. Common installation errors include incorrect thread orientation, over-tightening, and failure to align the lever with the flow direction.

Compatibility and accessories

This valve is compatible with standard gas piping systems using 6/4 inch FF connections. It is intended for use with low-pressure gas and should not be used with other media such as water or steam. No additional accessories are required for standard installation, but sealing materials such as PTFE tape or thread sealant should be used to ensure a secure connection.

Technical background for designers

The ball valve operates via a rotating ball with a bore that aligns with the flow path when open and blocks it when closed. The lever provides a mechanical advantage for smooth operation. The nickel-plated brass CW617N construction offers resistance to corrosion and wear, making it suitable for long-term use in gas systems. The FF thread ensures a secure and leak-tight connection. The valve's performance is influenced by the quality of the installation, the condition of the piping, and the operating temperature and pressure.

Service and operation

Regular inspection of the valve's lever and connection for signs of wear or leakage is recommended. The valve should be operated periodically to prevent seizing. No scheduled maintenance is required under normal operating conditions. If a leak is detected, the system should be depressurised and the connection inspected for damage or improper sealing.

Frequently asked questions

Can this valve be used with water or steam?
No, this valve is specifically designed for gas applications and is not suitable for use with water or steam.

What is the maximum operating temperature for this valve?
The valve is rated for operation up to +60°C in gas applications.

Is it possible to replace the lever with a different type?
No, the lever is an integral part of the valve and cannot be replaced separately.

Can this valve be used in outdoor installations?
It is not recommended for outdoor use due to the lack of weather protection. It should be installed in a dry, protected environment.
